AC repair in Eagan starts with a $79 trip charge, waived when you approve the repair. A first-generation condenser from the late 1980s or 1990s likely uses R-22, and a leak there points toward replacing it. The flat-rate price is written before we start.
Summer repairs in Eagan split by equipment age. Houses from the late 1980s and 1990s that never replaced their first condenser run R-22, and a leak on one of those is where repair and replacement start to compete. Newer R-410A systems from the 2000s mostly fail on electrical parts: a swollen capacitor, a pitted contactor, a fan motor with dry bearings.
Two-stories bring the familiar warm-upstairs complaint, and before blaming the condenser we check the filter, the blower speed and whether the coil is icing from poor airflow. In townhome rows, condensers sit side by side along a common wall, where one unit can blow its hot discharge into the next and the coils collect grass clippings from mowing. A condenser that can't reject heat trips on overload, which from inside looks like an AC that works in the morning and quits by mid-afternoon.

Check the timing. If it only happens while the AC runs, the likely source is condensate: a clogged trap, a cracked drain pan or a condensate pump that has stopped pumping. A water heater leak doesn't care whether the AC is on. In a shared closet the two sit inches apart, so shut the AC off at the thermostat, towel it up and call us. We'll trace which one is wet and price the fix in writing.
Often the condenser can't shed its heat. A coil matted with grass clippings, a weak fan motor or capacitor, or, in a townhome row, a neighbor's unit blowing hot air into yours will trip the compressor on overload as the afternoon heats up, and it restarts once it cools. With the power off at the disconnect, check that the coil is clear. If it keeps happening, we test the capacitor, fan motor and pressures and give you a written flat-rate price before replacing anything.
